Image Texture scaling
The problem is that there are 2 UV maps (&quot;UV_Channel_1&quot; and &quot;...2&quot;) but they are empty (or broken).

To fix them delete the UV maps and create new UV maps for all parts of the couch.
With the mouse in the 3D viewport and in Edit Mode, press U for unwrap menu, then select &quot;Smart UV Project&quot; from the menu, and you will have a working UV map.

(The bottom part of the couch needs some manual adjustments in the UV editor or scaling.)
Last but not least:
In the render settings, under Color Management, set View Transform to &quot;Filmic&quot; to get a natural look of the light/exposure. You can set the Look to &quot;High contrast&quot; if you want to have richer colors.
(And of course, add some more lights to your scene ;-)
